After being diagnosed with cancer, many people's lives have become more "refined". They used to have no meat, no pleasure, late night snacks, not giving up leftovers, and malnutrition... Now, bad eating habits have gradually improved. , pay attention to nutrition, and also start to pay attention to taboos: soybeans, old hens, fish, beef and mutton can't be eaten... In fact, these can be eaten, but the real taboos are these 6 types of food.

Taboos 1

Grapefruit, Seville oranges, star fruit, pomegranate and corresponding juices - these are taboos when taking targeted drugs/chemotherapy

There is nothing wrong with fruits, but they affect the activity of CYP3A enzyme in the body during the metabolic process, which in turn affects the metabolism of drugs and affects the efficacy of drugs, especially grapefruit (also called grapefruit).

It has been reported in the literature that grapefruit can affect some diseases including etoposide, olaparib, crizotinib, erlotinib, gefitinib, cabozantinib, everolimus, The efficacy of imatinib, lapatinib, nilotinib and other drugs [1]. Therefore, it is better not to eat these fruits while taking targeted drugs/chemotherapy.

Grapes, oranges, grapefruits, and pomeloes are not grapefruits and can be eaten.

Taboo 2

Royal jelly, royal jelly, bird's nest, snow clam, placenta - taboo for breast cancer

As we all know, sex hormones are related to breast cancer It is closely related to the occurrence and development of breast cancer. In particular, continued increase in endogenous estrogen levels or exogenous estrogen supplementation can significantly increase the incidence of breast cancer [2]. Therefore, breast cancer patients should pay attention to these estrogens in their daily diet. More food.

It is rumored that breast cancer patients should avoid soy products, honey, hens, and eggs. In fact, this is not necessary. All cancer patients do not.

Food taboos 3

Garlic, ginger, angelica – food to avoid when using anticoagulant drugs

These foods/medicines will change the anticoagulant effect of anticoagulant drugs. Strong, increasing the risk of bleeding [3].

The blood of tumor patients is often in a hypercoagulable state and is prone to thrombosis. It is not uncommon for tumor patients to use anticoagulant drugs: bedridden tumor patients and tumor-related surgeries need to prevent thromboembolism and venous thromboembolism. Cancer patients (incidence rate 4-20 [4]) need thrombolysis [5]...

Commonly used anticoagulant drugs are:

Taboos 4

Ginseng, Ginkgo biloba, milk thistle, plant-based supplements for treating depression - taboos during chemotherapy

(Milk thistle: some liver-protecting tablets contain milk thistle)

These foods/drugs can interfere with the CYP2D6 enzyme in the body, reduce the effectiveness of chemotherapy drugs, or poison the human body by preventing the complete decomposition of the drugs [3].

Food taboos 5

Foods containing carcinogens - taboos for all patients

According to the "World Health Organization International Agency for Research on Cancer Carcinogens List - Category 1 Carcinogens" Food List (***120 items)》These common foods/medicines must be avoided. Category 1 carcinogens are definitely carcinogens for humans, but it does not mean that you will get cancer after just one bite. There is a dose issue, but to be on the safe side, it is recommended to avoid eating them.

Understand Class 1 carcinogens

Food taboos 6

Foods high in fat, sugar, and starch—appropriate food taboos for all patients

The main problem with these foods is that they can lead to overweight or obesity. Overweight or obesity is related to at least 13 different types of cancer [6], and it also increases the risk of death and recurrence of some tumors [7].

Sugary drinks may directly promote tumor growth and progression, independent of obesity [8]. Appropriate avoidance of high-fat, high-sugar, and high-starch foods is of great benefit to cancer patients. Switching to natural foods is safe and healthy.

Pay more attention to your diet, and it will take less effort to fight cancer.
